makefile-awk-help-regex-must-include-digit-character-class

Makefile help text generation using awk to parse targets excluded targets whose names contained digits (test-a11y, k8s-apply, prod-up). The awk regex [a-zA-Z-]+ must be extended to [a-zA-Z0-9-]+ to capture digit-containing target names. Bug is silent — targets simply disappear from make help output with no error.
